They were removed and in their former form, unlikely to return. Simply put, they were random "I win" things in many situations, and in others, they were useless. Sure 1 extra talent made things easier, but those random freak chances of 3 DT's by Military Base were just insane. They made things easier at random, and also they permitted dual T3's. Moreover, and this wasn't overt most of the time, but sometimes it was, it encourage one to whore as much as possible in order to play the lotto of getting DT and just lead to a snowball effect (Get DT, gain massive killing power from early T3, whore like nuts, power level, go to step 1).
